Answer:

Step-by-step explanation:
Use the inverse cosine function.



Answer:
12
Step-by-step explanation:
the number is 96
hence,
25% of 96=
25/100*96/1
=24
50% of 24=
50/100*24/1=
12
it also possible that you're to sum them,but since you were not asked for the sum of the number the answer is 12.
B
Step-by-step explanation:
Answer:
The correct answer is option D. 13
Step-by-step explanation:
From the figure we can see two matrices A and B
<u>To find the sum of a₃₂ and b₃₂</u>
From the given attached figure we get
a₃₂ means that the third row second column element in the matrix A
b₃₂ means that the third row second column element in the matrix B
a₃₂ = 4 and b₃₂ = 9
a₃₂ + b₃₂ = 4 + 9
= 13
The correct answer is option D. 13

Volume of a Cylinder Formula: V = πr²h
- <em>r</em> is radius
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables.</em>
<em>r</em> = 5 cm
<em>h</em> = 10 cm
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Cylinder Formula]: V = (3.14)(5 cm)²(10 cm)
- [Order of Operations] Evaluate: V = 785 cm³
